TELEPHONE;

Application filed January 28, 1927. Serial no.'1e4,231.

My invention relates to improvements in telephones, and 1t conslsts 1n the comblnations, constructions, and arrangements, hereinafter described and claimed.

An object of my invention is to provide a telephone in which the receiver and the transmitter are connected together so that both of them may be manipulated by one hand and in which the switch is automatically opened when the telephone is placed in an upright position.

A further object of my. invention is to provide a device of the type described in which the weight of the telephone is. utilized for closing the switch and which provides novel means for permitting the telephone to be placed upon a supporting surface and still keep the switch closed,

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is lllustrated in the 510C011}:- panying drawing, forming a part of thls application, in which-.-

Figure 1 is a front elevation of the device,

Figure 2 is a vertical section thru a portion of the device,

Figure 3- is a section along the line 33 of Figure 1, and

Figure 4 shows the device disposed. in a position for keeping the switch closed.

In carrying out myinvention, I provide a. triangular shaped stand 1 having an upright 2 extending therefrom, this upright having an eyelet 3 at the top thereof. Near the top of the upright 2, I mount a receiver 4, and upon the upright, I slidably dispose a trans-- mitter 5; Figure 4 clearly shows how thetransmitter 5 is connected to a sleeve 6, which moves upon the upright 2.

The upright 2 is preferably made of a conducting material, while the connecting memher 7 which secures the transmitter to the sleeve 6, and the sleeve are made from insulating material. The sleeve 6 carries a contact 8 which bears against the insulated portion 9 of the upright 2 when the sleeve is in the position shown in Figures 1 and 2. When the sleeve is moved into the dotted line position (see Figure 1), the contact 8 will touch a conducting portion of the upright 2, thus closing a circuit between the wire 10 (see Figure 1), receiver 4, wire 11, upright 2,0011- tact 8, wire 12, transmitter 5, and then to wire 13.

In Figure 2, I show the sleeve 6 as being provided with a push button catch 14, this catch having a projection 15 receivable in a recess 16. A spring 17 urges the projection 15 into the upright 2.

From the foregoing description of the I various parts of the .device, the operation thereof maybe readily understood. When a person Wishes to use the telephone, he grasps the sleeve (3 and lifts the device, bodily, from the supporting surface. At the same time,-he presses upon the push button 14, thus causing the upright 2 to move down-' wardly with respect to the sleeve 6 and the transmitter 5 and to make an electrical connection with the contact 8. The mouth portion 18 of the transmitter '5 is inclined (see Figure 4) for permitting the person to readily talk into the transmitter when placlng the receiver .4 against the ear. The telephone switch is opened when the device is again placed upon the supporting surface in the position shown in Figure 1. In case the operator wishes to keep the circuit closed, and, atthe same time, place the device upon the supporting surface, he disposes the device a switch, said switch being closed when said sleeve is moved with respect to said support, means for locking said sleeve to said support when the switch is in open position.

2. A. telephone comprising a support, a movable sleeve for lifting the support bodily, a switch, said switch being closed when said sleeve is moved with respect to said support, means for locking said sleeve to said support when the switch is in open position, and means for disengaging said 'locking means.

3. A telephone. comprising a support, a sleeve slidably mounted on said support and adapted to drop to its lowermost position by gravity, a switch, said switch being open in the lowermost position of said sleeve and wards on a supporting surface, so as to maintain said sleeve in its uppermost position.

4. A telephone comprising a base, said base to hold said telephone in an upright position, a support extending from said base, a slidable sleeve carried by said support, and a switch actuated by said sleeve, said switch being closed when said sleeve is moved with respect to said support, and means for locking said sleeve'to said support when said switch is in open position.

5. A telephone comprising a base, said base to hold said telephone in an upright position, a support extending from said base, a slidable sleeve carried by said support, a switch actuated by said sleeve, said switch being closed when said sleeve is moved with respect to said support, means for locking said sleeve to said support when said switch is in open position, and manually operated means for releasing said locking means.

6. A telephone comprising a base, said base to hold. said telephone in an upright position, a support extending from said base, a receiver secured to said support, a slidable sleeve carried by said support, a transmitter carried by said sleeve, a switch actuated by said sleeve, said switch being closed when said sleeve is .moved with respect to said support, a spring actuated projection mounted in said sleeve for locking said sleeve to said support when said switch is in open position, and a manually operated plunger for releasing said projection.

In testimony whereof I ailix my signature.

CHARLES H. SEDGWICK.
